signor, by mesne assignments, to The American Bicheroux Company, a corpo'ation of Delaware Application March 12, 1931, Serial No. 522954 In Germany April 7, 1928 4 Claims. (CI. 49-3) My invention herein disclosed relates to the manufacture and leering of glass sheets produced at a high ,speed of formationand moved :forward during the cooling and annealing period at a speed slower than that of the rate of formation. For this purpose it comprises a high speed intrmittent sheet forming machine and a roller conveyor receiving the sheets from the machine as formed and consisting of a series of sheet 1 carrying rollers, some of which at least are driven at a peripheral speed less than that of sheet formation, which lower speed will be here'- inaiter termed the leering speed, together with a high speed sheet feeding mechanism consist-` ing of rollers acting on the upper surface of the sheet and driven with a peripheral velocity higher than leering speed. It further consists in the construction, arrangement and combination of the several parts as will be hereinafter more 2 iully described and claimed. p

Referring to 'the accompanying drawing in which corresponding parts are designated by ccrresponding marks of reference Fig. 1 is a fragmentary vertical longitudinal view oi' a 5 structure embodying my invention.

Fig. 2 is a vertical transverse section therec taken through line 2-2 of Fig. 1.

Fig. 3 is a iragmentary side elevation.

In the drawing a is an intermittent running machine, ,preferably of the Bicheroux type, adapted to fabricate, and to deliver down the incline apron c, sheets of glass b.

Located below the lowerend of the apron is the sheet conveyor comprising the series of roll- 3 ers d and the series of rollers a. The rollers d are driven with a peripheral speed the same as the speed at which the plate is delivered from` the forming machine or slightly higher and the rollers a are driven at a lower speed i. e.. leering speed. These last named rollers may be enclosed in the leer j.

Located above certain oi' the rollers g at the entrance 'end of the leer are rollers h adapted to be' driven at the same speed a's 'the rollers d',

i.e. at !orming speed. The direction ot the r'otation of the rollers h is contrary to that of the rollers g, and each roller h; is vertically above one of the rollers g.

The rollers d are shown as driven from a sha'i't othrough the beveled gears p. The rollers a are driven through-the beveled gears r by the longitudinal shaft q, an overrunning clutch r' being inte'rposed between the shaft and the rollers g at the entrance end oi' the leer, to

permit such latter rollers at times to be driven by the glass thereon. The shaft q is shown as driven from the shaft o by a speed reducing gearing o'.

The rollers h have bearings in boxes h' and .are mounted for a limited vertical movement in oo guides h? and are at times lifted in such guides by the rcds k fastened at their upper ende to bell cranks l. The several bell cranks I are connected together and may be rocked by the link m when actuated by themagnet n. os

The rollers h are driven by the shait w having interpcsed along the link thereof worms t, connected with the shaft by universal joints :c and carried in bearings v attached to the boxes h' on the upper rollers h. The worms mesh with worm-wheels s on the end of the rollers h and the shaft w, driven at the desired speed by the motor e.

In the operation of the apparatus just described the sheet as it is delivered from the apron c is received on the rollers d and is moved forward thereon at speed ot Iormation or at a slightly higher speed by\ which it is stretched as it leaves the apron. It is delivered by the rollers d onto the rollers a and so under the rollers h which are at this time raised to permit such delivery. After the sheet passes under the rollers h the latter are lowered onto thetop of the sheet and being driven at high speed feed the sheet forward at high speed on the rollers g, which at such time are driven by the sheet, this being permitted by the oven-unning clutches. The sheet is fed forward at this speed bythe rollers h for a time sufiicient to permit it to further harden, and after passing oo under the rollers h it is carried forward at leering speed by the rollers a.

This application is a continuation in part of my prior application No. 351487, filed in the United States Patent Ofllce on April 4, 1929.

Having thus described my invention what I claim is:

1. In combination with a high speed intermittent sheet glass forming machine, of a conveyor receiving the sheet as the same is Iormed, the conveyor' comprising two seriesoi' rollers, the rollers of the first series being driven with a peripheral speed substantially equal tothe speed of sheet formation and the rollers ot the second series being driven at a lower speed, and 106 a series of rollers driven at 'a peripheral speed substantially equal to the speed oi sheet formation, each roller of the last named series being located vertically above a conveyor roller oi' the second series. ll(

2. In combination with a high speed inter-mittent sheet glass forming machine, ot a conveyor receiving the-sheet as the same is rormed, the conveyor comprising two series of rollers, the rollers ot the first series being driven with a peripheral speed substantially equal to the speed of sheet formation and the rollers of the second series being driven at a lower speed, an overrunning clutch interposed in the drive for the last named rollers, and -a series of rollers driven at a peripheral speed substantially equal to the speed ot sheet formation, each roller of the last named series being located vertically above a conveyor roller of the second series.

3. In combination with a high speed intermittent sheet glass forming machine, of, a conveyor receiving the sheet as the same is formed, the conveyor comprising two series of rollers,

the rollers ot the first series being driven with 'a peripheral speed substantially equal to the speed of sheet formaticn and the rollers of the second series being driven at a lower speed, a.

.rollers o! the first series being driven with a peripheral speed substantially equal to the speed or sheet formation and the roilers of the second 'series being driven at a lower speed, an overrunning clutch interposed in the drive for the last named rollers, a. series of rollers driven at a peripheral speed substantially equal to the speed oi' sheet torn ation, each roller of the last named series being located vertically above a conveyor roller of the second series, and means tor raising and lowering the last named rollers.
